What Does FPB Stand For?

FPB stands for Fuel Preburner

FPB, or Fuel Preburner, is a component used in rocket propulsion systems to ignite and initiate the combustion of fuel before it enters the main combustion chamber. By preburning a portion of the fuel, the FPB enhances engine efficiency and performance, leading to improved thrust and reduced emissions. Its design is critical for ensuring stable operation during the critical phases of rocket launch and flight.
